How to limit the total number of emails sent in cPanel on all accounts

Cpanel has a tool to help control the number of outbound emails sent, this is useful especially when your email scripts are compromised. The following steps will allow you to lower the outbound email limits, or increase them depending on your needs.

Log into WHM

Go to Tweak Settings

Go to the Mail section.

Fin the setting named “Max hourly emails per domain”. By default its set to Unlimited however you are able to set a value for it.

If your server is under high load because of outbound mail you can start with setting this to 100, to lower the load and allow you to check the accounts and ensure they are not compromised.
